HEATER.

Application filed April 21, 1920, Serial No. 375,561. Renewed February 1'7, 1922. Serial No. 537,358.

To all whomit may concern.

Be it known that I, ALBERT R. J. DEARDEN, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Heater, of which the followin is a description.

lIy invention relates to a heater and more particularly to a heater in the form of a radiator and having, heating means.

The general object of the invention is to embody in a heater of the indicated character, a novel arrangement of flues forming a circulation circuit in coaction with the heat-producing means with a view to the eflective application, utilization and radiation of the generated heat.

A more specific object of the invention is to produce a practical embodiment of the invention reflecting important practical considerations withrespect to simplicity of construction and facility of assemblage, adjust-- ment and repair.

The above and other objects as will appear are attained by a heater possessing the distinctive features and combinations of parts as hereinafter particularly described and defined in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a longitudinal vertical section of a heater embodying my invention;

Figure 2 is a transverse vertical section on the line 2-2, Figure 1;

Figure 3 is a transverse vertical section on the line 33, Figure-1.

Figure 4 is a view showing a valve-controlled vent in elevation.

In carrying out my invention in accord-. ance with the illustrated example, the heater is made to embody a series of vertically dis posed radiator sections 10. These may be formed in any suitable manner and in practice the sections are separately cast. or formed of sheet metal. Each of the sections, or at least the central section, may be made up of corresponding halves, the making of the central section .in halves being with a view to the assembling of the burner and the nozzle associated therewith as hereinafter referred to. Said sections are assembled side by side and held together. by suitable means such as longitudinal tie rods 11, 12. One radiator section is arranged to constitute an uptake flue for the air products of combustion and forms part of the circulating circuit including a downtake flue or flues and cross connections between the same and the uptake flue. Advantageously, the uptake flue designated 10 is central, there being a series of downtake flues 10 at each side thereof. The communicating openings 10 are provided in the radiator sections at the top of the fiues to constitute in eflect a transverse flue establishing communication between the downtake flues at their upper ends and the uptake flues. Suitable means is arranged to deflect the ascending air and gases laterally from the uptake flue, 10, to thedowntake flues, 10". Said deflecting means in its preferred form consists of an arched element 13 disposed transverseappurtenances. The burner may, as shown,

take the form of a transverse jet tube 14: disposed at the bottom of the uptake flue 1O transversely thereof. Over the burner 14 I providea nozzle .15 disposed transversely in the flue 10 the walls of said nozzle being convergent above the jet tubeld. One end 16 of-nozzle 1 5 is open and extends through a side or the radiator section 10 to afford access to the jet tube 14 for lighting the burner, the open end having a suitable movable closure 17. The burner being of the Bunsen type, the gas connection 18 therefor is conveniently arranged near the open end 16 of nozzle 15 as well as air inletopening 19,, the jet tube presenting interiorly an approximately vertical surface 20 against which the incoming air and gas currents inr pinge for mixing.

Lateral openings 10 are formed in the several sections 10 and constitute in effect a. transverse return flue establishing communication between the downtake flues 10 and the uptake flue 10 and with a burner and nozzle employed as described the nozzle will terminate at the openings 10 so that the nozzle discharges to the uptake flue 10 adjacent to the openings 10 at each side of the nozzle. The walls defining the openings 10 are flaring so that the opposed walls at opposite sides of the nozzle 15 converge upwardly as viewed in vertical section through the walls, the result being that the walls of the openings at the top and the nozzle tip constitute in effect injector elements to assist in drawing the air laterally through the flue represented by the openings 10 to the uptake flue 10 In addition to the transverse return flue constituted by the openings 10 I produce a lower series of communicating transverse openings 10 in the radiator sections constituting in effect a second return flue between the downtakes 10 and the uptake 10 and the jet tube 1% is disposedin the plane of said openings 10 to draw air toward the burner and afford an ample supply of oxygen to sustain combustion. The lowermost transverse flue constituted by the openings 10 it will thus be understood, functions more particularly in connection with the fluid fuel burner. a

With the above described construction, the heat-producing means being in action an active upflow will take place in fine 10 and the current will be deflected laterally by the deflector 13 in opposite directions into the upper transverse flue produced by the openings 10 from which transverse flue the air and gas currents will be drawn downwardly through the downtakes 10 under the suction induced in the transverse flues represented by the openings 10, 10 due to the influence of the injector action at the top of the nozzle .15 and the action of the burner tube id.

The arrangement of the circulating lines,

as described, lends itself to the disposing of one transverse tie rod 11 to pass through the upper transverse flue produced by openings 1.0 and the other tie rod 12 in the lower-v most transverse flue represented by the openings 10*. The ends of rod 11 extend through the outer sections 10 and said sections have vent openings 21 optionally controllable by turnable dampers 22. Similarly, the lower rod 12 in flue 10 extends through the end radiator sections 10. i 7

At the ends of the transverse flue repre-- sented by. the openings 10, said flue is open to the atmosphere through the medium of series of. small openings 2-3, 24, oneseries above the, other,permitting ingress of air or egress of air and hot products, the upper and lower series of openings permitting egress through the upper series simultaneously with ingress of air through the lower series or ingress or egress through both series according to the heat and pressure conditions.

The height, that is to say, the effective length of the downtake flues 10, will in practice not exceed the critical point of induced down draft effective under the suction produced in the transverse flue represented by the openings 10 (plus the suction in flue represented by the openings 10 and as the effective down draft influence has its limitations the radiator may advantageously be made of a height'independent of these limitations to the end that an ample radiating surface is produced. The radiator sections 10, may, as shown, be made to rise a Substantial distance above the upper transverse flue produced by openings 10 to thereby present above said flue and communicating therewith, vertical pockets 1O within the respective sections 10, said pockets factoring in inducing circulation within the radiator as will appear.

The several radiator sections may embody a feature known in radiator construction, to wit; vertical slots 25 in the sections at each side of the openings 10, 10 These can be made to terminate at the top at such a point that the heated currents passing transversely through the openings 10 can rise in the different radiator sections to take a downward course and not be confined to passing through. the downtake flues 10 to the central space between the walls 26 of the slots 25. In any event the suction produced in the lower flue represented by the openings 10 will be effective in producing a downward suction in the spaces of a downtake flue 10 at the outer sides of the walls 26, thus causing more or less of, the hot air and products to rise at the flue represented by the openings 10 and pass over the walls 26 and downwardly. At the same time, there is an effective down draft induced in the central space between the pair of slots 25 and directly downwardly from the openings .10 to the openings 10 in addition to the circulation outside of the slots 25 and their walls 20. v

The down flow through the outer vertical. spaces in the rad ator section (outside of the slots 25 and their walls 26) due to the suction induced by the lower flue formed by the openings 10 is in practice also assisted by the fact that the heat in the central space between the two slots 25 and walls 26 is much more intense than in the outer spaces so that in effect there is a counteracting em pansi'on of the air in the central space simultaneously with a cooling contract-ion of the air in the outer spaces, the currents being given, in this manner, a tendency to pass dowulwm'dly in the outer spaces as well as in the central spaces where the suction is more directly effective.

At the ends of the rods 12 simple riveting will suffice but I prefer to employ cup-shaped ashers 2'7 beneath the heads to simulate the dampers or valves 22. I would mention here also, that in. practice I may form air inlet holes 2-8 in thecentral'radiator section adjacent to the burner or, other source .of heat. The numeral 29 indicates opposed projections on the respective sections, the projections of a pair being in position to engage each other and brace the sections when assembled as known in radiator construction.

Reverting to the slots 25' and the spaces or columns into which the radiator sections areI thus divided, it will be understood that the number of slots in the respective sections may vary and indeed the provision of any slots is not necessary to the invention in all its phases. The slots, however, are preferred since in addition to increasing the radiating surfacethey are utilized for an important function, as follows: It will be observed from Figure 3 that the slots 25 are omitted from the central sections, the uptake 10 having u'nslotted walls, which are highlyheated and cause the air to rise at both sides of the central section between the same and the adjacent sections, which are spaced by the walls of the openings 10", 10, 10 The result of the highly heated central section is that the air will be drawn through the several slots 25 toward the central section and will rise adjacent to the latter, thereby circulating the air. Thus, the heating is by conduction, distributing the heat throughout the sections; by convection due to the circulation of the air through the slots inwardly to the central section, and upwardly at the sides of the latter; and by radiation of the heat from the various sections.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, 1 do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.
